Have a new open station 4066r that I like very much except the amount of exhaust. Even though the exhaust is directed below there is still exhaust coming out of the exhaust vent on the hood. Is this normal or is there something that can be done to stop this. Any suggestions would be appreciated.

Have you looked for exhaust leaks under the hood? Might need to it checked under warranty.

Tier 4 engines do some odd stuff. Even odder how JD has 2 exhaust pipes (one just a vent on top of the hood & the other under by the frame)

Thanks for the replies. Since my last post the dealer has tightened up the butterfly valve near the vertical exit and the amount of exhaust coming out seems less. Not perfect, but better.
